A former pilot suffering from blackouts discovers that a fellow flyer is suspected of being mixed up with a web of smugglers. While searching for his missing buddy, he unwittingly becomes entangled in a morass of suspicion.
After a bit of counter-play with "Van Ness" (Zachary Scott) - the brother of his girlfriend, "Nick" (Robert Beatty) sets off on a routine flight in horrid weather near the Channel Islands. The plane crashes and the ensuing police investigation starts to uncover evidence of a network of criminal activities and it falls to "Van Ness" to schmooze "Alexia" (Kay Kendall) and try to find out just who is pulling whose strings. It's all rather pedestrian, this. Scott and Kendall deliver well enough with the rather clunky script but Beatty is as wooden as his aircraft and the sense of menace that we get a hint of at the start, peters out quickly leaving us with a rather ordinary afternoon feature from Terence Fisher that just about fills seventy minutes with little jeopardy or story of note and a rather stage-bound look to it.
